The Photo Eye panel defines the position and type of the Photo Eye.
The following properties are on the Photo Eye panel:
Defines the X, Y, and Z position of photo eye.
Defines the height of the photo eye.
Defines how far along the photo eye's conveyor the photo eye is positioned. Changing this value will update the Position.
The amount of time a photo eye must be covered before it will change from a blocking state to a blocked state.
The amount of time a photo eye must be clear from items before changing from a clearing state to a cleared state.
The offset angle by which the photo eye beam crosses the conveyor plane. If 0, the beam crosses straight across the conveyor.
If checked (default), there must be a gap between items in order to clear the photo eye. You might uncheck this box if you want the On Clear trigger to fire on every item, no matter the spacing between items.
Defines the method for calculating whether the photo eye is "covered" on a mass flow conveyor. The following options are available.
Defines the ratio of the maximum flow unit density that will trigger the blocking/ clearing of the photo. The value should be between 0 and 1. The value 0 means nothing is in front of the photo eye, and 1 means the conveyor is at full capacity in front of the photo eye.
Defines the speed threshold of flow units in front of the photo eye that will trigger blocking/clearing.
Defines the photo eye's color. This is the color displayed when the photo eye is in the "cleared" state. The colors for the "blocking", "blocked", and "clearing" states are defined on the properties of the Conveyor System.
